Question 499352: Hi. I need help in solving this rational expression.
R = Rate in mph of Husband
R + 10 = Rate of mph of Cherie
Driver Distance Rate
Cherie 150 r + 10
Husband 100 r
Same time = distance / rate
Cherie 150/ r + 10
Husband 100/r
So solve 150/r + 10 = 100/r

If you want to solve 150%2Fr%2B10=100%2Fr multiply every term by the LCD r to get 150%2B10r=100. From here, just solve this as you would any other equation.

Assuming you mean:
150%2F%28r%2B10%29+=+100%2Fr
.
Cross-multiply to solve.
.
150%2Ar+=+100%2A%28r%2B10%29
150r+=+100r+%2B+1000
50r+=+1000
r+=+20
